Insulated Glass

INSULATED GLASS

Insulated Glass Units, or IGUs are constructed with two or more panels of glass separated by a desiccant filled  Aluminium spacer that is hermetically sealed with either polysulfide or silicone and the insulating airspace is filled with air or a noble gas, such as argon or krypton inside, as these gases are denser than air and less likely to let heat conduct through the IGU which would provide better insulating performance to enable the glass to meet two very different requirements – keeping heat in during colder weather and keeping heat out during warmer weather.

Insulating glass units have many advantages for energy saving, the insulated glass is a very effective way to reduce air-to-heat transfer through the glazing, especially combined with a Low-E or reflective coatings, these gases work to improve the window’s overall u-value, which is a measure of the heat transmission through a building part (such as a wall or window). The lower the u-value, the better the insulating glass unit. Low-E and other coatings provide substantial improvements – up to 50 percent in U-values and solar heat gain coefficients compared to uncoated insulating glass units.

Sound insulation performance: single layer glass can reduce noise o 20-22dB. Insulated glass can reduce noise to 29-31 while special insulated glass to 45dB. 

Anti-dew: Double glazing glass is filled enough desiccant which can efficiently absorb vapor in the inner space or penetrated from outside to ensure the gas in inner space is absolutely dry and won't dew.
